Option A, They contain a thick tunica media

Explanation:

Artery consist of tunics which is made up of three distinct layers

a) The internal layer is tunica intima - made up of epithelial and connective tissue layers

b) The middle layer is tunica media - thickest layer in arteries and consists of layers of smooth muscle supported by connective tissue

c) The external layer is tunica externa - sheath of connective tissue composed primarily of collagenous fibers
